Mix Proportion Design of Phosphor Building Gypsum-based Cementitious Material Based on Gray System
摘要
Abstract
The phosphor building gypsum-based cementitious material was prepared by Yunnan phosphogypsum as main ingredient. The influence of each component of phosphor building gypsum-based cementitious material on its dry compress strength was analyzed by gray relational analysis method,and determine fly ash,slag Portland cement silica fume and phosphor building gypsum as its optimum admixture;On the basis of this combination,the weighted multi-attribute intelligent gray target decision model was used to investigate comprehensively the six indexes of compressive strength,flexural strength, initial setting time,final setting time,softening coefficient and porosity,and determine its best mix ratio. Tests show that:The phosphor building gypsum-based cementitious material with the composition of the ratio of fly ash: slag Portland cement: silica fume: phosphorus building gypsum =6%:5%:3%:86%works best,its dry compressive strength can reach 14. 11 MPa,flexural strength can reach 2. 58 MPa, initial setting time is 16 min,final setting time is 43 min,the softening coefficient is 0. 51,the porosity is 23%.关键词
